To all whom it may concern Bc it known that l. llriiox Kixxnann. a citizen ot the l nitcd States'. and resident of Aurora. county ot' `Kane. and State'ot Illinois. haveinvented certain iicw and useful improvements in Bucket Convevers` oi which the:following is a specification. and which are illustrated in the accompanying drawings, forming a part'thereot.

The `invention relates to conveyer which conipi'isea lpair of sprocket chains between which Vare pivotally carried a series of buckets. a ftripper being provided tor' turning the buckets for the purpose ot' dischargingl them of their contents.

The. objects of the invention are to provide A.ineansl for completely' overturning or rotating the buckets for the purpose of'discharge; to provide lfor such tripping operationl whe-'n thc'convever is driven in either direction: and to provide iii'iproved meansl for preventing the tiltingot' the buckets as they are filled. These ob'iects are attained in. the -structure hereinafter'described and which is, illustrated in the acconipanying drawings in which l Figure 1 isa detail side elevation ot' the conveyer. Fig. 2 is av detail side. elevation thereofjsonieof the parts being omitted,

drawn toa larger scale. and showingthe.

tripper aiid thema-nner of its operation. is a .transverse sectional detail on the line 3'3 of Fig. 2. Fig. l is a transverse Sectional det-ail on'the line A oit' Fig. l, and Fig. 5 is a longitudinal sectional detail through a portion ot -a pair of buckets,'

The conv'eyer is shown as adapted to .receive material at one l level and discharge it a't a higher level, there being provided a succession of sprocket wheels .designated by' the' Y numerals 10, 11, 12 and 13 which are mounted upon suitable supports and 'are arranged in the form of a parafll wheels are mounted inpairsbut in thedrawings only one member-of each Mounted upon thes'e sprecket wheel'sai'e a pair of chains 14:` 15, each chain comprising a succession of links pivotally united` the pivots carrying flanged wheels 16 which run upon lower and lupper horizontal tracks 17, 17 and are 'engaged by the several sprocket; wheels. A succession of buckets as 18. 19, 20, 21 and 22 are carried by thetwo chain being pivotally attached to the links lograin, In practice itA will be understood ,that vthese sprocketl pair isshown.-

thereof, preferably intermediate of their yends. each bucket being provided with loi`igitudinallv projecting lips 13. Q-l. om` at eafch cud` the lips otl adjacent buckets overlapping. I As thus i'ai-l described the apparatus conf torinslo common practice. 'llie bucket.`l are. ol considerable \\"cight and their. pivots or gudgeons arc so disposed that 'they are maintained in proper or upright positioiibv gravity. .\s Athe bucketsl are transferred from the ascendiiig'strctch ot' the 'chains lo tht` upper horizontal stretch their forward lips naturally take the positioirbeloiv the rearward .lipsl of the next preceding bucket. -l-lcietofore it hasl been thepractice to discharge the buckets ot' their' contents byftilting them. the bucket being periti/tinted to swing back .into normal position when empty. thus bringing its t'orward lip again in contact with the lower face ot the rea'iward lip of the uextpreceding bucket. a conseipieuce' as each bucket. starts on its 'descent it' must disengage itself from the 4next bucket in the rear and as a result both buckets are caused lo swing. "In consequence of the very considerable weight of the bucketsthere results a disagreeable claiiging and frequently considerable damage to vthe parts. As the buckets receive their loads as theyY travel along the' ,lower hori- `zoiital stretch ot' thc'chains they are apt to be tilted and permit the nn'iterial to drop between them particularly when it contains heavy blocks'. To overcome the former ot thesel diHicultie's l provide an iiiipi'o\'cdforni of tripp'er mechanism whereby the bucket .i's completely overturned or rotated in the discharging action, thereby more ellectualli1 discharging it of its contents and bringing its forward lip above the rearward lip of the next bucket in. advance. When thus arranged the descending bucket leaves the following bucket Without 'any interference. whatever. To this end there is fixed to each end of each bucket -a trippingcam generally designated by the numeral Q5 and being. provided with-a depending arm 26 and two laterallyv projecting arms QT. Q8 at its upper end. The tripper is in tho Jorino'f 'a carriage' 99 having supporting wheels 30. 3l which run upon the track 32. thusI permitting it to be shifted toany desired position alone' theupper horizontal Stretch of the sprocket chains.' The two side rails of the tripper 29 are alike' and are provided at Y standing-.lug 3d forin `each 'end y.with 'upstanding .lugs .33, lSlot suiimcntheight to. engage vthe depending --a'r'in 26 of .the tripper cani 'As' vthe depending arin'of thetripper cani.

As cachot1 the bucljets enters up .ony the lo'wer-horizontal stretch vo i the chains its forward lip naturally locates y itselhabove .the rearward -lip of the iextprecedin T bucket. As this would cause an intel-ten. ciji'ce', as each bucket starts 'upon its upward travel afteijvbein'g loaded itis advisable to .-readjust. their' relative relations so as vto bring lthe or'ward ward lipof the next bucket in advance, before filling.
